means of which this shaft is connected with ortion of the differenthe worm formingl a w ich the drive shaft is tial assembly wit associated.

An im ortant object of the invention is to provid a device of this character which may be very readily applied to the'drive shaft and coupling and which will greatly facilitate removal of the shaft from the coupling.

A further object of the invention is to rovide a device of this character which may Be ver readily and chea ly manufactured and w ich will be durab e and eificient in service.

These and other objects I atta by the construction shown in the acco panying drawings, wherein for the purpose of illustration is shown a preferre embodiment of my invention and wherein 2- igure 1 is a sectional view showing a puller constructed in accordance with my lnvention applied to the shaft to remove the coupling therefrom;

' Figure 2 is a side elevation thereof as 30 applied to the shaft;

igure 3 is a section on the line 3-3 of Fi re 1.

eferring now more particularly to the drawings, the numeral 10 generally indi- 5 cates the drive shaft of an automobile and v 11 'a coupling by means of which the drive shaft is connected with the worm 12, which forms a portion of' the differential assembly with which the shaft is associated.

In accordance with my invention, I provide a puller comprising male and female elements '13 and 14 adapted toengpfie the cou ling and shaft respectively. e fem e element has a bore 15 receiving the 45 shaft and has directed through its body setscrews 16 extending radially to the bore and adapted to engage the shaft 10 and hold the female element against movement thereon. The bore 15 communicates with an enlar d o bore 17, the wall of which is provided with screw threads for engagement with threads formed upon the exterior of the male member 13. The male member 13 has a bore 18 shdably receiving the shaft and is formed at one end with a polygonal head 19 with which a wrench may be enga ed.

In the use of the device, t e drive shaft having been removed from its housin (not shown), the male member is threadefi into the female member as far as it will go and the assembled uni-t slid upon the shaft 10 with the male member in advance until this male member comes in contact with the coupling. The set-screws 16 are then tightened to hold the female member firmly against any movement with relation to the shaft after which a wrench may be applied to the male member 18 to jack the coupling from the shaft.

It will be obvious that b use of a device of this character, the coup ing may be ve readily removed without marrin the she at a point where the shaft has aring in its mounting.

It will also be obvious that the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention and I accordingly do not limit myself to such specific structure except as hereinafter claime I claim I In a device for removing couplings from shafts, a female member havin at one end a bore adapted to receive and shdably fit the shaft, means projecting through the wall of the member at said end for holdin the member a ainst displacement longitu inal- J.YRAPPLEY.
